Understanding risk assessments
You, as the employer, are the one who stands between your workers and an accident!
• Look at what can
hurt you or your
workers;
• Decide what you
are going to do;
• Write down what
you are going to
do;
• Tell your workers;
• Do it!

A short guide to risk assessments
The following pages include examples of dangerous situations on site and how you can manage similar situations to protect the
health and safety of your employees.
Undertaking risk assessments is not difficult! In essence it requires you to look at your workplace and identify where people can be
harmed. Then you need to
do something to prevent that harm from happening. Take these simple steps
and you will be
providing a safer workplace for you; your employees; and other people
close by.
Next
look at the level of
risk. Some hazards will be
high risk, e.g. working at
height. Other hazards will be a lower risk,
because the harm may be less severe.
“What is the chance people
will be harmed and how
serious could the injury be?”
Start by
looking at “hazards”
that are at your site. A
hazard is simply anything
that can cause harm to you or your
employees.
“Where can people come to
harm?”
Then tell your employees!
Decide what you are
going to do to make the
site safer for you; your
employees and other people
around you.

Simple steps that you can follow!
• Look at your workplace, what can harm me or other workers on site.
• As an employer, you should ask yourself:
• “Can I get to my workplace safely?”
• “Can I work there safely?”
• “What is the level of risk?”
• “Who is exposed to the hazards?”
• “What can I do to make it safer for me and others around me?”
• Keep the workplace clean and safe!

Look - Act!
Different trades
will be undertaking
different
construction
activities on site.
As an employer,
you must look at
the tasks that your
employees are
carrying out and
work out what the
level of risk is to
their safety.
This is part of the
risk assessment
process.
Here we are looking
at steel erection,
which is a high risk
activity.
You must act to
minimise the risks.

Preventing injury
Typically 15% of non-fatal injuries
in the construction sector involve
injuries to the fingers. A further 8%
of non-fatal injuries involve injuries
to the hand.
You need to consider all levels of
risk of harm; not just the high risk
activities. Non-fatal injuries can have
a lifelong debilitating effect - protect
your employees!

Simple steps that you can follow!
• Read the instructions for the particular dumper you have;
• Drive within safe limits across sloped ground/banks;
• Check tyres and brakes;
• Always use the seat belt when roll over protection systems (ROPS) are
fitted. Check that ROPS is certified and has CE Marking plate attached;
• Check that nobody is at risk of injury before moving off, particularly in the
area obscured by the skip when going forward, and behind the vehicle
when reversing;

Quick and Easy!
If you are operating
a machine (e.g. a
360 o excavator)
then you are
responsible for
the safe use of the
machine, including
the correct use of
the quick hitch.
Make sure that
the safety pin is
fully inserted into
the quick hitch.
The attachment
must be properly
attached before
you use it. Always
check!
Never swing the
attachment over
other workers or
allow them to work
directly under the
attachment.

Risk assessment: What is “likelihood”?
The first thing to think about
when doing a risk assessment is
“How likely is it that someone
can be harmed by this hazard?”
The likelihood of someone being
harmed varies depending on the
environment, the work activities
and how often someone is going
to be exposed to the hazard.

Using your experience and
knowledge, you should be able
to work out the likelihood quickly
and easily.

Risk assessment: What is “consequence”?
Major
injuries
The next issue to consider is the
consequence (or severity) of the
hazard; “How serious could the
injury be?”
The severity can be influenced
by the environment and the
provision of a safe place of work
and a safe system of work.
Minor
injuries

Major injuries, ranging from permanent
disability to death
Using your experience and
knowledge, you should be able
to work out the severity quickly
and easily.
Increasing SEVERITY of injury
You must put appropriate control measures in place, for all levels of risk, including low risk.

Controlling the risks: SSWP can help you
Where it went wrong
We have looked at three examples where it has gone wrong on construction sites. As an employer,
you need to make sure it does not go wrong on your site. To help you, the Health and Safety
Authority has produced the Safe System of Work Plans (SSWP). The primary objective of the SSWP
is to identify the major hazards associated with your work activities and to ensure that appropriate
controls are in place before work commences. The SSWP is a three-part process:
• Part 1: Planning the activity;
• Part 2: Hazard Identification, and Control Identification;
• Part 3: Sign off.
There are currently six SSWP Construction Forms available, including forms for House Building;
Ground Works; Demolition; Civil Engineering; New Commercial Building; and Working on Roads.

Risk assessments: Summary of key components
You must carry out risk
assessments, as part of your Safety
Statement. Write these down and show them
to your employees.
Here are the three key
components of a risk
assessment.
When you
know each of the hazards
that are there on site, you
need to assess the level of
risk that you and your employees are exposed to.
This is a simple step to take, just think about how
likely it is that you could be harmed by each hazard
and then how seriously you could be hurt. This will
help you to rank the hazards. Some will be high
risk, others medium risk or low risk hazards.
Take a good look at the
construction site and the
work that you are doing
there. What you are looking
for are the situations where
people can be harmed (e.g. hazards). This can
include people other than your employees. Look
at how you get to your work area on site, is there
safe access? Look at how you carry out the
work, how can you be harmed?
At this
stage you should have a
written list of hazards and the
level of risk for each of these.
You now need to decide what you are going to
do about each hazard. Talk to your employees about
the hazards. Write down the control measures and
show these to your employees. Using the SSWP
that is best suited to your work, will help you
carry out risk assessments.
